Experience some strange behavior since this week.
The taskbar icon near the clock disapears. After pressing ctrl+alt+del and starting taskmanager I see there is still a process running.
Problem exist on Windows 7 x32 and x64 on loggedin administrator as well as on “normal” users.
Saw the problem also on computer of a collegue so I suppose it’s not username related.

That’s pretty much where I’ve been, too. I’ve been pretty safe just killing the process in task manager & restarting it to get the tray icon to show up again. I can’t promise that you won’t lose keys that way – but I personally haven’t. So I think you should be safe.
As for what’s causing it – as bobL explains, explorer crashing is common. I think I’ve had it happen by other means, but I just can’t remember what they are.
